合成了配合物二(N－质子化亚氨基二乙酸)锰(Ⅱ)并于293（2） K用X射线测出了其晶体结构.晶体为四方晶系，空间群为p42_1c， a=0.805 7(1)　　nm, c=0.955 1(3) nm, V=0.620 0(2)nm3, Z=2, Mr=355.17, Dc=1.902mg/m3, F(000)=366, μ=1.125mm-1.对于465独立反射点［I>2σ(I)］,其R因子为0.019　6,Rw为0.055　3.每个Mn(Ⅱ)与来自四个配体［NH2(CH3COO)2］-中的四个羧基氧原子及两个来自水分子的氧原子配位，形成变形八面体结构.锰（Ⅱ）之间通过桥基配体相联，整个晶体呈层形网状结构，层与层之间通过配体水分子中的氢与未配位的羧基氧、及质子化的氮原子上的氢与未配位的羧基氧之间的氢键相联. The complex of bis (N-protonated iminodiacetic acid) manganese (Ⅱ) was synthesized and its crystal structure was determined by X-ray at 293 (2) K. The crystal was tetragonal with space group p42_1c, a = 0.805 (1) nm, c = 0.955 1 (3) nm, V = 0.620 0 (2) nm3, Z = 2, Mr = 355.17, Dc = 1.902 mg / -1. For the 465 independent reflection point [I> 2σ (I)], the R factor is 0.0196 and the Rw is 0.055. Each Mn (II) is related to the ligands from four ligands [NH2 (CH3COO) Of the four carboxyl oxygen atoms and the two oxygen atoms from the water molecules coordinate to form a deformed octahedral structure.Mn (II) is bridged by a bridge ligand, the entire crystal was layered network structure, layers and layers Through the hydrogen atoms in the ligand water molecules and the uncoordinated carboxyl oxygen, and the protonated nitrogen atoms on the hydrogen and uncoordinated carboxyl oxygen hydrogen bonds between the associated.
